This machine adopts synchronous control technique, welding time and cent-control welding are composed of PLC program system with pressing firmly once only and welding repeatedly. The input front-panel has two forms: touch screen and keyboard, it makes this machine more intelligent and reasonable. The weft supplies are automatic. The greatest advantage is that you can adjust the distance of cross at random on one piece of mesh sheet. This machine equipped with new and efficient transformer, whose gear shift has 8-class, so it enlarges welding range .It is easy to learn and use, and welding output is more several times than manual work.
